If something isbetween an occupant and an air bag, the bag might not inflate properlyor it might force the object into that person causing severe injury or even death. The path of an inflating air bag must be kept clear. Don't put anything between an occupant and an air bag, and don't attach or put anything on the steering wheel hub or on ornear any other air bag covering. Don't let seat covers block the inflation path of a side impact airbag. When Should an Air Bag Inflate? If your vehicle has one, the right front passenger's side impact air bag is in the side of the passenger's seatback closest to the door. Frontal Air Bags The driver's and right front passenger's frontal air bags are designed to inflate in moderate to severe frontal or near-frontal crashes. But they are designed to inflate only if the impact speed is above the system's designed "threshold level." 1-72
